Zoom in: Nearly a dozen streets will close to vehicles from Thursday at 10pm to Monday at 6:30pm, including several blocks of Constitution Avenue and 17th and 15th Streets (squint above).

• No-parking zones will start earlier, at 6am Thursday, and run until Monday night.

On Friday, a UFC press conference at the Lincoln Memorial will close nearby streets and Memorial Bridge, from 6pm to midnight.

• The bulk of the dozens of street closures and parking restrictions will take effect on Friday evening through early Monday.
• D.C. police urge residents to check online for updates.

State of play: Leading up to Sunday's bout on the South Lawn, the UFC will host a weigh-in ceremony Saturday evening at the Ellipse.

• Delays are expected at National Airport during flyovers of Apache attack helicopters on Saturday and Sunday, authorities said on Wednesday.

Federal and local law enforcement will partner on security, with Secret Service deploying hundreds of officers, drones and tactical teams. Not to mention "unseen resources," said Secret Service Washington office chief Tara McLeese at a Wednesday press conference.

• The live screening of the fight on the Ellipse will have "TSA-style" security screenings and "only small clutch bags will be permitted," McLeese added.
